SIX Damn AMPLWER

©

The AB International ProfeSSional Series Model
6300A is a six channel full featured Amplifier.
This compact instrument (four rack unit) is
equipped with three individual power supplies,
six independent balanced and unbalanced inputs,
detented level controls, signal present and " Soft
Clip" indication, convection cooled with tem-
perature activated fan assist, Stereo/Bridge
switches per each two channels. The 6300 deliv-
ers 200 Watts into 8 Ohms, 300 Watts into 4
Ohms and 500 Watts into 2 Ohms all six channels
driven from 20Hz to 20kHz at .l% distortion.

Model 6300A incorporates a three year Five Star
protection plan featuring the following unprec~
edented circuitry. VI energy limiters are incorpo-
rated for short circuit protection. if an extreme
low impedance exist, a current sensing circuit will
reduce the output to prevent amplifier overdrive

If an abnormal high AC line voltage is present or an
excessive voltage surge appears, the amplifier will
detect the situation and turn itself off. If an unlikely
DC situation occurs, DC sensing circuits will trigger
the amplifier channel and turn off. Thermal sensors
are installed in each channel to prevent an over
temperature condition. "Soft Clip" circuitry has
been incorporated for added protection to prevent
hard clipping from improper use.

A rear panel 100Hz Linkwitz Riley fourth order Lo-
Pass filter switch has been added to channel Six for
subwoofer applications. Other features included are
internal selectable input sensitivity, ground lift
switch and fully modular design for service accessi-
bility. 70v transformers are available in a variety of
options for distributed systems.

The Model 6300A operates from 1001240V SO-
GOHz AC Mains and measures 7" high (four rack
unit), 19" wide and 14" deep.
